I This invention relates tovtie plates particu-.rbody portion 12 of the tie plate with the forlarly for couplingchains and specifically for ward .end of the eye bent downwardly so as coupling tire chains, that is, the stringer and to provide a substantially triangular orifice cross chains which makeup the tire chain for to form theeye.

I

It will be noted in Figure 1, and in dotted lines in Fi ures 4: and 5, that the resilient: member 16 at its forward end substantially spans the bight of the hook from the bill tothe shank portion 14 thereof. This positioning of the resilient member or spring plate 16 forms an enclosure for the link of the cross chain 11 which is in engagement with the hook and prevents that link from shifting back away from the bight of the 'hook, so that the parts are held in snug normal position as distinguished from construc- "tions in which the spring retaining member does not span the bight of the hook, but merely guardsthe bill of the hook, leaving the entire hook aperture open for play of the link. l T:

In order that the links {of the cross chain 11, which are commonly fashioned in a figure-8 formation, may liein a natural position relative to the hook portion of the tie plate and each other, and prevent any distorting strain on theend link of the cross chain, I preferably provide the hook between the bight and the end thereof with seats or depressions 19 on each side of the hook and offset on each side of the longitudinal center thereof so that, as shown in Figure 3, the

3 limbs of the cross chain link 11 will lie within the. seats 19 and in a normalundistorted position. The seats 19 may be formed in any desired way, but preferably, and as here shown, will .be formed by bending the end of the hook, as clearly illustrated in Figures .1, 2, 3, and 4, this bend being graduated from the end of the hook to the bight of the hook from maximum to zero.

With the parts thus assembled the cross chain may readily be snapped into the hook by engaging the end of the link with the spring plate adjacent the bill of the hook and plate with then by a half'turn or twist of thelink of the cross chain against the spring plate, it .may. be engaged with the hook and brought to the position shown in Figure 1. The re 'moval of the 'crosschain 11 for renewal, repair, or adjustment may be readily made by forcing the link against the end of the spring plate and past the bill of the hook, the

relation of the bill of the hook and the end of the spring platebeing such as to facilitate the engagementand disengagement of the cross chain link.

" WVhile this is the preferred embodiment of my invention, it will be understood-that the hook portion may be formed without these seats but embodying the other features of novelty, as shown in Figure 5.

A chain tie plate having a hook at one end, an eye at the opposite end, and a resilient hook closing member, the rear end of which abuts the'rear wall of said eye to prevent pivotal shifting of said resilient member, the

forward wall of said'eye being bent down wardly into clamping engagement with said resilient member;

7. A chain tie plate having ahook at one end, an eye at the opposite end, and a flat hook closing spring secured to said plate with its rearend abuttin'g'the rear wall of said eye to preventpivotal shifting of said spring, the forward wall of said eye being bent downwardly into clamping engagement 8. A chain tie plate having a hook at one end, an eye at the opposite end, and a flat hook closing spring secured to said plate, the rear end of which spring abuts the rear 3 wall of said eye to prevent pivotal movement of said spring, the forward end of said spring I substantially spanning the hook from its bill to its shank to prevent a part engaged by the hook from moving out of the bight of the hook. V

9. A chain tie plate having a hook provided on opposite sides with ofi'centered seats to receive the limbs of a hook-engaged link.

10. A chain tie plate having a hook bent in opposite directions longitudinally to form ofi'centered seats on opposite sides to receive the limbs of a hook-engaged link.

11. A chain tie plate having a hook provided with ofi'centered seats on opposite sides inclined from the bight of the hook toward its end.

12. A chain tie plate having a hook bent to form ofl'centered seats on opposite sides inclined from the bight of the hook toward the end to receive the limbs of a hook-engaged link.

13. A chain tie plate having a hook bent to form oflcentered seats on opposite sides inclined from the bight of the hook toward the end to receive the limbs of a hook-engaged link. said seats being inclined from the bight of the hook toward its end.

14. A chain tie plate having a hook bent to form ofi'centered seats on opposite sides inclined from the bight of the hook toward the end to receive the limbs of a hook-engaged link, said seats being inclined and flared outwardly from the bight of the hook toward its end.

15. In a chain tie plate, means permanently to attach said plate to a stringer chain, said means comprising a substantially triangularly shaped closed eye at one end ofthe plate, a hook member for attachment to a cross 45 chain at the other end of the plate and provided with means to prevent distortion of the cross chain, and means secured to the plate to prevent disengagement of the cross chain from the hook.
